Abstract
Aim: Diagnostic accuracy of magnetic resonance angiography inprediction of intracranial aneurysms in post coiling patients taking digital subtraction angiography as gold standard.
Methodology: It is across sectional study in department of Neuro-Radiology, Lahore General Hospital, Lahore from 21-01-18 to 21-06-18. 136 cases were enrolled. Patients with intracerebral coiling of brain aneurysms underwent MRA and findings were noted. Then these patients had four vessel cerebral DSA and findings were identified. Data was analyzed on SPSS version 20.
Results: The mean age was 41.03±11.98 years.M:F ratio was 2.1:1. The mean duration of coiling was 8.1±1.8 months. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of ICA-MRA was 88.2%, 92.9%, 88.2%, 92.9% & 91.2% respectively.
Conclusion: MRA is very useful noninvasive procedure in follow up for post-coiling cerebral aneurysms in diagnosingrecurrence of aneurysm.
